 What pollutants do CleanWay® stormwater filtration systems remove?
CleanWay systems are designed to remove stormwater pollutants ranging from small particulates to trash and debris, depending on the configuration. Our filter media captures total suspended solids (TSS), sediment, oil sheen, heavy metals and more.
How long do filtration inserts last?
As a general guideline, the filter element must be replaced annually. More frequent element changes are dictated by site conditions. The cleaner the site, the longer the service life between maintenance cycles.
How do you know when it’s time to change the filter?
Monthly inspections, which are required for most permit holders, provide visual clues. It’s time for maintenance:
- when the rigid strainer insert is dirty and debris has accumulated in the strainer
- when the water level in the strainer rises above normal levels—which is seen during rain events
- when water samples taken from the unit show water quality decay or degradation
What type of maintenance is needed?
First, the grate is removed to access the catch basin. Second, the rigid strainer is easily accessible and can be removed by hand, then emptied in an approved receptacle. Third, to perform maintenance on the filter element, a vactor truck, vacuum truck street sweeper or large shop vac can all be used to remove accumulated pollutants and debris.
How do I remove specific pollutants—what options do I have?
We offer a variety of filter elements and adsorption media to meet your site-specific requirements. Along with standard configurations, we provide special sizes and configurations according to your specifications. Contact us to learn more or provide a quote.
Do I need regulatory approval to use CleanWay products?
Because all of our products are intended for use as retrofit or as part of a larger treatment system, approvals are not required. However, we recommend that you check with your local regulatory entity for any special considerations.
How can I tell if the filter is working correctly?
CleanWay catch basin inserts and Downspout filtration systems all feature our proprietary sampling port. The sampling port is large enough to introduce a typical sampling bottle and is readily accessible and easy to use. Simply take a sample with a dip stick with cup and view or analyze the contents.
How do I know if I need a custom or standard product?
Because of the wide variety of inlet sizes and shapes in use, we have developed a diverse inventory of standard products to fit most applications. Just give us a call or complete the Filter Sizing Guide and we can quickly determine whether one of our off the shelf standard products will fit your site.
Do you also provide maintenance for your systems once installed?
We offer maintenance through our Partnership Program, working with various service providers to maintain your systems on regular intervals. Contact us for a service provider in your area.
Or, your current stormwater facility maintenance provider can also perform the required services.
How often does the Adsorb-it Filtration Fabric element need to be replaced in a typical parking lot application?
CleanWay Adsorb-it Filtration Fabric sorbent products remove oil, oil sheen, and suspended solids from water. We recommend installation of new Filtration Fabric elements at the start their rainy season. For example, say we install a new element in the northwest on or around the first of October. Once the leaves have fallen from the trees—around the end of November—we replace the element again. This second element may last through the remainder of the winter rainy season. That depends heavily on the condition of the pavement, the volume and type of traffic, the area of pavement that the filter serves and the weather conditions. To perform at its best, the filter element should be replaced regularly if it is exposed to oily grit.
If neglected, the filter will become clogged and water will start to flow out the bypass. No treatment of this bypass water will be achieved. Simple visual inspection of the filters on a monthly basis is all that is usually required to determine if the element needs to be replaced.
Filtration Fabric elements are very inexpensive and simple to replace. We encourage people to replace the element at the first indication that it is starting to become clogged.
